xv HABITS OF ANOMAZ.17RUS 463
A.nom.alurus peli appears, according to Mr. "W. H. Adams,1 to
be a common species on the Gold Coast; it is coloured black and
white, but in spite of the warning which this colour should
convey, is considered by the perhaps rather omnivorous native as
" the greatest delicacy." The animal is nocturnal, but affects only
bright moonlight nights. Their " flying " consists of a jump from
a high branch to a lower one, after which they reascend the tree
to a point of vantage for another jump. They are said to feed
upon nuts; but Tullberg only found the remains of leaves in the
IdiiLrus is a lately-described genus allied to ^inornalurus.
There are at any rate two species, I. zenk&ri and I. macrotis.
The thumb is more reduced than in -AtiowialuTus., and the fibula,
contrary to what is found in that genus and in most Sciuromorplis>
is fused with the tibia below.
A third genus, very recently described and allied to both the
foregoing, is ^Agthurus. It is a native of the French Congo,2 and
differs by the absence of flying membranes. It has, however, the
pad of large scales. There is but one species, A. glirinus. It
has a black bushy tail. The postorbital processes of the frontals
are totally wanting---there are not even the traces to be seen in
The thumb has vanished. If we are to compare
with the Squirrels then, thinks Mr. de Winton, the
present genus is probably diurnal by reason of the want of flying
Fam. 2, Hciuridae.—The Squirrels, genus /$C'iii,m6sf are world-
wide in range, the Australian region and the island of Madagascar
being alone excepted.
The eyes and the ears are large; the tail is of course long
and bushy. The fore-feet have an inconspicuous thumb; the
hind-feet have four toes. The soles of the fore-feet are
naked or furry, those of the hind-feet are hairy. There are
twelve or thirteen dorsal vertebrae, and in correspondence seven
or six lumbars. The caudal vertebrae may be as many as twenty-
five. In the skull the frontals are broad, and there are long
